Non exhausting labour
The funny thing about workers is that they pay their own bills AND the bills of the employer (assuming a company is cash flow positive), whereas the employer only puts up an initial set of funding, which gets expired, and they rely on workers for income, so why do capital owners get paid again and again for the same funding but workers don't?
The unfairness of capital. I propose labour is treated the same way as capital, as in it is non-exhausting. Whereas a capital owner is owed the capital they put in and all its growth, a labour is only entitled a single fee. This is morally and ethically wrong.
